The Dark Realm The majority of the information available is what the Silent Walker has chosen to reveal, or that of legend. The Dark Realm is the realm of which the Beings of the Dark choose as their domain or prehaps were exiled there, though they effect many others, each with their own area. The Realm itself is only accessable from Cephta, existing on the same yet not the same dimensional plane as Cephta.

MazokuThe term "Mazoku" is used for all of the high powers and their direct servants. IE this term would be used for the Silent Walker, Death, Time, the Beings of the Dark, and their servants. Mazoku are not completely evil, but their usual behavior is "evil" and tend to have malviolent tendencies.
There are creatures generally called Lesser Mazoku. These creatures are not Mazoku however, having more of the status of demons which are under Mazoku. Also tending to be actually evil.

EarringsEarrings are one way of telling who a Mazoku serves. Each servant wears what their master wears. It is also a symbol of status. Status is very important and sometimes a life or death situation. If the servant does not have visible ears, then they will wear it on a necklace or on some other form.
